The advisory urges airline staff to provide surgical masks to potential Ebola victims in order “to reduce the number of droplets expelled into the air by talking, sneezing, or coughing.” (emphasis mine).

The CDC is also directing airline cleaning personnel to, “not use compressed air, which might spread infectious material through the air.” (emphasis mine).

Researchers demonstrated that the virus could be transmitted from pigs to monkeys without any direct contact by placing the two animals in pens separated only by a wire barrier. After eight days, some of the monkeys were found to have symptoms of Ebola likely as a result of “inhaling large aerosol droplets produced from the respiratory tracts of the pigs.”

The results of the study led scientists to conclude that, “limited airborne transmission might be contributing to the spread of the disease in some parts of Africa,” although they cautioned against making comparisons to the airborne nature of the influenza virus.
